HORACE WV. BRAY, OF PANA, ILLINOIS.

PHOTOGRAPHIC BURNISHER.

SPECIFICATION forming part of Letters Patent No. 261,200, dated July 18,1882.

Application filed May 16, 1882.

To all whom it may concern:

Be it known that I, HORACE W. BRAY, a citizen of the United States ofAmerica, residing at Pana, in the county of Christian and State ofIllinois, have invented certain new and useful Improvements inPhotographic Bur nishers; and I do hereby declare the following to be afull, clear, and exact description of the invention, suchas will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersor figures of reference marked thereon, which form a part of thisspecification.

This invention relates to certain improvements in presses used inburnishing plates in photography; and it consists in the form of theburnishing-plate, the manner in which it is supported upon pivotedhearings, in the devices employed to elevate and depress it, and in thegeneral combination of these elements, all of which will be hereinaftermore particularly described, and set forth in the claims.

In the drawings, forming a part ofthis specification, Figure 1 is a sideelevation of the press. Fig. 2 is a transverse section of thebnrnishing-plate. Fig. 3 is a sectional elevation of one of thestandards, showing the pivoted support of the burnishing-plate. Fig. atis a View of the under side of the plate.

A is the base-plate of the press, of the usual thickness for stabilityand strength. ()n this base A are two standards, B B, each having twoinclined legs, as seen in Fig. 3. In the leg B of each standard aregrooves b I) for the admission of a bar, 0, which is level on its topedge, but has two wedges, c, on the bottom edge, as seen in Fig. 1. Thebar 0 has a handle, a, by which it is to be moved, and in one of thelegs B thereis a set-screw, b, by which the bar (J can be made fast,when desired.

D is the burnishing-plate, and is formed in cross-section, as seen inFig. 2, like a saddletree, having the wings (I d drooping down in acurve below the seat at d d. Fig. 4 shows this plate to be hollowed outin the form of an (Model) oval dome, with the top flattened somewhat, asshown in dotted lines in Fig. 1. The insides of the wings d d areribbed, as seen in Fig. 4, to strengthen them to resist the pressure andyet to be thin enough for the heat imparted by the lamp underneath, asseen iii-Fig. 3.

E E are the supports of the burnishing-plate D, and are pivoted stronglyto the inside of the legs of the standards B B, as shown ,at c, Fig. 3.On the top of these supports are seats ee,

. sunk a little below the top, forming a recess for the flanges d d onthe bottom of the burnishing-plate D at each end. The side of thesupports E opposite to the pivot e rests upon the top edge of the bar 0,and when the bar 0 is at its lowest point the burnishing-plate D can beeasily removed from the recesses e e on the supports E E. The sliding ofO in the other direction forces the supports E E far enough upward tocarry the burnishing-plate up to the roller F, which is supported insuitable bearings on the top of the standards B, as seen in Fig. 1,where the handle G is fastened to the end of the roller. A lamp forburning gasoline va poris placed upon a stand, a, which is secured tothe base-plate A. The dome shape of the burnishing-plate serves to catchall the ascending heat from the burner below, and the ribs serve tostrengthen the wings.

I claim 1. The combination of the burnishing-plate with the pivotedsupports provided with recesses for seating the plate, substantially asshown and described.

2. The combination of the bar 0, provided with a double wedge, thesupports on each side pivoted to the standards, the burnishing-plate,and the roller, substantially as and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.

HORACE W. BRAY.
